Shell Offshore, Inc. announced a large, deep-water, exploration discovery in the Norphlet geologic play in the US Gulf of Mexico with its Dover well (100% Shell).

The Dover discovery is Shell’s sixth in the Norphlet and encountered more than 800 net feet of pay (244 meters). The discovery is located approximately 13 miles from the Appomattox host and is considered an attractive potential tieback. Shell’s Appomattox host has now arrived on location in the US Gulf of Mexico and is expected to start production before the end of 2019.

Dover showcases our expertise in discovering new, commercial resources in a heartland helping deliver our deep water growth priority. By focusing on near-field exploration opportunities in the Norphlet, we are adding to our resource base in a prolific basin that will be anchored by the Appomattox development.

—Andy Brown, Upstream Director for Royal Dutch Shell

Shell’s major, deep-water hubs are well positioned for production expansion through near-field exploration and additional subsea tiebacks. The company expects its global, deep-water production to exceed 900,000 barrels of oil equivalent per day by 2020, from already discovered, established areas.

Shell’s Dover discovery was drilled by the Transocean Poseidon, new build rig, in the US Gulf of Mexico.

The well was drilled in Mississippi Canyon Block 612, located approximately 170 miles (273 kilometers) offshore southeast of New Orleans, in a water depth of 7,500 feet (2,280 meters) to a total vertical drilling depth of 29,000 feet (8,839 meters) measured depth. Appomattox host platform is owned by Shell (79%) and Nexen Petroleum Offshore USA Inc. (21%).
